Alright guys - I want to theorize on this a bit. Plus, I don't have enough advanced chemistry knowledge to know the specifics of how one would actually pull it off, aside from literally going the old fashioned "test it myself" route. So - with that said, here's my theory / question: Is it possible to extract the "essential oil" from an ethanol solution using a reverse osmosis filter? I was doing some research on my own, just looking for different techniques in the industry, and I happened to come across this patent: http://www.google.com/patents/US20120141644 . I know they aren't the same chemicals and stuff, but the technique itself sounds like something somewhat in the realm of replicatable, and considering the wide availability of reverse osmosis water filters on the market, it would be wonderful to be able to skip the QWET evap process after winterization, and just go straight to the essential oil extraction. Again, this is all just me theorizing, and I didn't see much discussion on the subject, so wanted to throw it out there and see what other people's thoughts were / if it was even possible.
